Subject: [PATCH v2 01/12] Remove USE_SIGTRAP_SIGINFO condition for FreeBSD/x86 debug regs support.
Date: Wed, 16 Mar 2022 13:19:12 -0700	[thread overview]
Message-ID: <20220316201923.89694-2-jhb@FreeBSD.org> (raw)
In-Reply-To: <20220316201923.89694-1-jhb@FreeBSD.org>

For BSD x86 targets, stopped_by_hw_breakpoint doesn't check siginfo_t
but inspects the DR6 register directly via PT_GETDBREGS.
